For precise measurements on parts, ATEC offers affordable laser micrometer and optical micrometer rental rates from leading manufacturers including Keyence, Mitutoyo, and Beta LaserMike.
What Is A Laser Micrometer?
An inspection device that uses a rotating laser beam to collect exact measurements and dimensions of a physical object, micrometers provide a highly accurate but 2D representation (as opposed to the 3D measurements provided by similar devices such as CMMs and 3D laser scanners).
Micrometers work by transmitting a laser beam from one end of a small measuring area to a receiver on the other end. The working principle is that when an object is placed in the measuring area it blocks the laser and creates a shadow on the receiver. The receiver calculates the time cast by the shadow to collect detailed measurements of the object.
Micrometers are crucial tools in manufacturing and NDT. In quality control labs and plant floor settings, part measurements need to be accurate down to the microinch. A laser micrometer rental guarantees physical analysis that is both detailed and reliable.
Choosing The Right Laser Micrometer Rental
The capabilities of laser and optical micrometers have improved greatly in recent years, but not every device is ideal for all testing needs. Before choosing a rental, consider these specifications and details:
Type
The first aspect to consider is which type of device is needed. There are four different types of laser micrometers, all built to measure in different ways:
- Benchtop or Floor Mounted: As the name suggests, this is stationary. Users will need to load and measure the objects manually.
- Automatic or Inline: Also stationary, these micrometers collect measurements without the need for user input.
- Machine Mounted: Either mounted in or on a piece of equipment, these devices are often used to help with tool setup.
- Portable or Handheld: Offering the most maneuverability, these are also easy to use as many have a helpful user interface.
Single-Axis Or Dual-Axis
A single-axis laser micrometer measures from one direction, collecting precise measurements for thickness, diameter, and position. Only needing one entry point, it is ideal for measuring objects with obstructions in the way such as wiring, steel, and moving parts.
A dual-axis micrometer conducts measurements from two perpendicular angles. With the extra angle, users can also measure for ovality, ideal for analysis on round, triangular, and rectangular objects such as pipes, cables, and optical fibers.
Measurement Range
Carefully consider the size of the object being measured in relation to the micrometer's range. If a product is too large or small for the measuring range, a micrometer might offer little help. One model may measure wires that are only 0.05 mm in diameter, while others can analyze objects up to 160 mm.
Benefits of Using a Laser Scan Micrometer
While many products excel with collecting precision measurements, precise analysis offers some key benefits.
Accuracy and Scanning Rate
Even when analyzing moving or vibrating objects, the measurements from a laser micrometer are exact thanks to its intricate working principle. An incredibly fast scanning rate ensures that any item can be measured with that same accuracy. Even a vibrating item can be captured by the scanning rate that exceeds 3000 scans per second.
Versatility
The single-axis and dual-axis micrometers cover many different varieties of objects, but advancing technologies now allow for measurements from a triple-axis micrometer. The improved measurement technique allows for even greater precision when determining diameter and the other minute details. Complex shapes and a variety of diameters are also easier to measure with a triple-axis micrometer.
Non-Contact Measurements
Laser scan micrometers are a non-contact measurement device. When collecting measurements, the lasers do not affect or harm even the most fragile objects. Products at both high and low temperatures are also easy to analyze. The non-destructive lasers also allow for measurements with incredibly high repeatability.
